Perhaps. But they are happy customers and their music sounds better.
Note: the dominating cost of -preempt is not Robert's patch, but the fact
that you need to have CONFIG_SMP enabled, even for uniprocessor, turning all
those stub macros into real spinlocks. For a dual processor you have to have
this anyway and it just isn't an issue.
Personally, I don't intend to ever get another single-processor machine,
except maybe a laptop, and that's only if Transmeta doesn't come up with a
dual-processor laptop configuration.

Was this on uniprocessor machines, or your dual Athlons? How did you measure
